Name of the Vulnerable Software and Affected Versions Pillow versions prior to 8.1.1

Description An issue was discovered in the TiffDecode.c component of the Pillow image processing library, related to a lack of memory volume check for reading, which can lead to a denial of service. The issue involves a negative-offset memcpy with an invalid size. This can be exploited by a remote attacker.

Recommendations For versions prior to 8.1.1, update to version 8.1.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the TiffDecode.c component until a patch is available.
